Referring to fig. 1 to 2, fig. 1 shows a cross-sectional view of an embodiment of a sweeping robot of the present invention, and fig. 2 is another view of the sweeping robot of the present invention.
Referring to fig. 1, in an embodiment of the present invention, a housing 10 of the sweeping robot 100 is provided with a mounting cavity 11, an accommodating cavity 12 and a dust suction channel 13; the mounting cavity 11 is communicated with a motor 20 of the sweeping robot and is used for mounting a cyclone cone 30 of the sweeping robot; the accommodating cavity 12 is concavely arranged on the lower surface of the housing 10, and is used for installing a floor brush 40 of the sweeping robot 100; the dust suction channel 13 is used for communicating the installation cavity 11 with the accommodating cavity 12, and the cross-sectional area of one end, adjacent to the accommodating cavity 12, of the dust suction channel 13 is 175-700 mm2。
The shape of the mounting cavity 11 is various, and may be cylindrical, square, spherical, and other shapes, which are not listed here; the mounting cavity 11 may be formed in various ways, and may be formed by surrounding different structural members, or may be formed during injection molding of the housing 10, which is not limited herein. The volume of the installation cavity 11 is larger than that of the cyclone cone 30, so that the cyclone cone 30 can be installed in the installation cavity 11 on one hand, and the dust, paper dust and other impurities separated by the cyclone cone 30 can be collected on the other hand.
The shape of the receiving cavity 12 can be varied, and it can be arranged in a long strip shape, a cylindrical shape, and other shapes, which are not listed here. The mounting cavity 11 may be formed in various ways, and may be formed by surrounding different structural members, or may be formed during injection molding of the housing 10, which is not limited herein. The volume of the accommodating cavity 12 is slightly larger than that of the floor brush 40, so that the floor brush 40 can be installed in the accommodating cavity 12, and dust, paper dust and other impurities brushed by the floor brush 40 can be sucked away quickly.
The dust suction channel 13 may be a linear channel, an arc channel, or a combination of a linear channel and an arc channel, which are not limited to the above. There are also various shapes of the cross section of the dust suction passage 13 in the radial direction, and the shape of the cross section of the dust suction passage 13 in the radial direction may be a circle, a square, a polygon, etc., which are not necessarily exemplified herein. Preferably, the cross section of the dust suction channel 13 along the radial direction is circular, so that the resistance of the dust suction channel 13 to the air is reduced, and the air flow in the dust suction channel 13 is facilitated. The dust suction channel 13 may be formed in various ways, such as a tubular structure, a plate-shaped structure, or an injection molded housing 10.
It should be noted that the suction force of the sweeping robot 10 is determined to ensure that the air in the accommodating chamber 12 can rapidly enter the mounting chamber 11, and the suction force of the dust suction passage 13 is ensured, and the suction force of the dust suction passage 13 is closely related to the size of the cross-sectional area (the cross-sectional area in the width direction). If the cross-sectional area of the dust suction channel 13 is too large, the air flow speed is too slow, and dust, paper dust and other impurities in the accommodating cavity 12 cannot enter the mounting cavity 11; if the cross-sectional area of the dust suction passage 13 is too small, dust, paper dust, and other foreign materials in the accommodating chamber 12 may easily clog the dust suction passage 13. In the embodiment of the invention, the cross section of one end of the dust suction channel 13 adjacent to the accommodating cavity 12 is 175-700 mm2On one hand, air in the accommodating cavity 12 can be ensured to rapidly enter the mounting cavity 11, so that the dust suction channel 13 is ensured to have certain suction force, and dust, paper dust and other impurities in the accommodating cavity 12 can be ensured to rapidly enter the mounting cavity 11 through the dust suction channel 13; on the other hand, it is ensured that the cross-sectional area of the suction channel 13 is larger than the dust, paper dust and other impurities, so that a blockage of the suction channel 13 is avoided.
According to the technical scheme, the housing 10 of the sweeping robot 100 is provided with the mounting cavity 11, the accommodating cavity 12 and the dust collection channel 13 for communicating the mounting cavity 11 with the accommodating cavity 12, the mounting cavity 11 is communicated with the motor 20 of the sweeping robot 100 and is used for mounting the cyclone cone 30 of the sweeping robot 100, the accommodating cavity 12 is used for mounting the floor brush 40 of the sweeping robot 100, and the cross-sectional area of one end, adjacent to the accommodating cavity 12, of the dust collection channel 13 is 175-700 mm2. So arranged, the floor sweeping is ensuredWhen the motor 20 of the robot 100 works, air in the accommodating cavity 12 can quickly enter the mounting cavity 11 through the dust suction channel 13, so that the suction force of the dust suction channel 13 is ensured, and further, dust, paper dust and other sundries brushed by the floor brush 40 can quickly enter the mounting cavity through the dust suction channel 13, so that the cleaning performance of the floor sweeping robot 100 is improved.
It should be noted that the floor brush 40 of the sweeping robot 100 is generally arranged in a long strip shape, which makes the accommodating cavity 12 for installing the floor brush 40 also arranged in a long strip shape, and the accommodating cavity 12 arranged in a long strip shape makes the spanning area thereof larger, so that dust, paper dust and other impurities in the position far away from the dust suction channel 13 in the accommodating cavity 12 are difficult to be sucked into the dust suction channel 13 if the spanning area of the accommodating cavity 12 is too large, and therefore, in an embodiment of the invention, the ratio of the cross-sectional area of one end of the dust suction channel 13 adjacent to the accommodating cavity 12 in the axial direction of the accommodating cavity 12 to the cross-sectional area of the accommodating cavity 12 in the axial direction thereof is set to be 1/12 to 1/6. Due to the arrangement, on one hand, the dust suction channel 13 can suck away dust, paper scraps and other sundries at various positions in the accommodating cavity 12, and the dust removal performance of the sweeping robot 100 is further improved; on the other hand, the problem of oversize design of the sweeping robot 100 is avoided.
Considering that when the accommodating cavity 12 is arranged in a long strip shape, the area spanned by the accommodating cavity 12 is relatively large, in order to adapt to the shape of the accommodating cavity 12 and improve the dust suction effect of the dust suction channel 13, in an embodiment of the invention, the ratio of the length of one end of the dust suction channel 13 adjacent to the accommodating cavity 12 in the axial direction of the accommodating cavity 12 to the length of the accommodating cavity 12 in the axial direction thereof is set to be 1/8-1/4. With the arrangement, the dust suction channel 13 can suck away dust, paper dust and other sundries at various positions in the accommodating cavity 12, so that the cleaning performance of the sweeping robot 100 is further improved.
In order to increase the suction force of the dust suction channel 13, in an embodiment of the present invention, referring to fig. 2, the inner diameter of the dust suction channel 13 is gradually decreased from the end adjacent to the accommodating chamber 12 to the end adjacent to the mounting chamber 11. So set up for the air can be quick enters into installation cavity 11 through dust absorption passageway 13, and then can promote this robot 100 of sweeping the floor's dust removal speed.
Further, the ratio of the cross-sectional area of one end of the dust suction channel 13 adjacent to the accommodating cavity 12 to the cross-sectional area of one end of the dust suction channel 13 adjacent to the mounting cavity 11 is 1-2. Due to the arrangement, on one hand, air can smoothly flow in the dust suction channel 13, so that the suction force of the dust suction channel 13 is ensured, and the dust removal effect of the sweeping robot 100 is further ensured; on the other hand, the dust suction channel 13 is not easy to be blocked by dust, paper dust and other sundries.
In order to facilitate the air in the accommodating chamber 12 to flow into the dust suction passage 13, in an embodiment of the present invention, the top wall of the accommodating chamber 12 is recessed away from the floor brush 40, so that a converging chamber 14 is formed between the top wall of the accommodating chamber 12 and the floor brush 40, and the converging chamber 14 connects the accommodating chamber 12 and the dust suction passage 13. When the air in the accommodating cavity 12 rotates along with the floor brush 40, the dust, paper dust and other impurities mixed in the air are easy to be retained and collected in the accommodating cavity 14, that is, the accommodating cavity 14 plays a role in containing the dust, paper dust and other impurities, so that the dust, paper dust and other impurities are easier to be sucked into the mounting cavity 11 through the dust suction channel 13, and the dust removal effect of the sweeping robot 100 is further improved.
Further, this converge chamber 14 is the concave cambered surface setting facing the chamber wall of scrubbing brush, that is to say, should hold between the roof of chamber 12 and the roof of dust absorption passageway 13 through the cambered surface connection, just so make and hold between the roof of chamber 12 and the roof of dust absorption passageway 13 smooth transition to be favorable to the flow of air, and then be favorable to holding the air in the chamber 12 and enter into in the dust absorption passageway 13 through converging chamber 14.
In addition, the top wall of the converging cavity 14 is in a concave arc arrangement, or the top wall of the accommodating cavity 12 and the top wall of the dust suction channel 13 are in smooth transition, that is, the top wall of the accommodating cavity 12, the wall of the converging cavity 14 facing the floor brush 40 and the top wall of the dust suction channel 13 are integrated, so that the accommodating cavity 12, the converging cavity 14 and the dust suction channel 13 can be obtained by opening a mold, and the production and manufacturing of the housing 10 of the sweeping robot 100 are facilitated.
In order to facilitate the air in the accommodating chamber 12 to flow into the dust suction passage 13, in an embodiment of the present invention, the top walls of the accommodating chamber 12 on both sides of the dust suction passage 13 are inclined to guide the air in the accommodating chamber 12 to flow into the dust suction passage 13. That is, the top wall of the accommodating chamber 12 is formed in a funnel shape, which facilitates the flow of air along the top wall of the accommodating chamber 12, and thus the flow of air into the dust suction passage 13.
It should be reminded that the floor brush 40 installed in the accommodating chamber 12 is driven by the driving device to rotate to brush up dust, paper dust and other sundries on the floor. Generally, the shape of the accommodating chamber 12 along the radial direction thereof is set to be circular or nearly circular, so that the air in the accommodating chamber 12 flows along with the rotation of the floor brush 40. One end of the dust suction channel 13 adjacent to the accommodating cavity 12 may be communicated with any position of the accommodating cavity 12, that is, one end of the dust suction channel 13 adjacent to the accommodating cavity 12 may be disposed through a side wall of the accommodating cavity 12 adjacent to the cavity opening, and one end of the accommodating cavity 12 adjacent to the accommodating cavity 12 may also be disposed through a top wall of the accommodating cavity 12 away from the cavity opening, which is not limited herein. Preferably, the dust suction passage 13 is disposed through the top wall of the accommodating chamber 12 adjacent to one end of the accommodating chamber 12 and tangential to the top wall of the accommodating chamber 12. Because the air in the accommodating cavity 12 is driven by the floor brush 40 and is driven by the motor 20, one end of the dust collection channel 13 adjacent to the accommodating cavity 12 penetrates through the top wall of the accommodating cavity 12 and is tangent to the top wall of the accommodating cavity 12, so that the air in the accommodating cavity 12 can enter the dust collection channel 13 more easily under the action of centrifugal force and the motor 20, thereby facilitating the entry of dust, paper scraps and other sundries in the accommodating cavity 12 into the dust collection channel 13 and further facilitating the dust removal effect of the sweeping robot 100.
Considering that the accommodating cavity 12 has a certain length, in order to ensure that dust, paper dust and other impurities at various positions in the accommodating cavity 12 can be sucked into the dust suction channel 13, one end of the dust suction channel 13 adjacent to the accommodating cavity 12 is communicated with the middle of the accommodating cavity 12, that is, the distance from the two ends of the accommodating cavity 12 to one end of the dust suction channel 13 adjacent to the accommodating cavity 12 along the axial direction of the accommodating cavity 12 is approximately equal, so that it is ensured that the suction force of the dust suction channel 13 to the two ends of the accommodating cavity 12 is equivalent, and the dust suction channel 13 can suck the dust, paper dust and other impurities at the two ends of the accommodating cavity 12, that is, the dust suction channel 13 can suck the dust, paper dust and other impurities at other positions of the accommodating cavity 12, so as to improve the cleaning effect of the cleaning robot 100.
Considering that the air, dust, paper dust and other impurities entering the installation cavity 11 are collected in the installation cavity 11 under the separating action of the cyclone cone 30, and the air is exhausted, so as to facilitate the removal of the dust, paper dust and other impurities in the installation cavity 11, in an embodiment of the present invention, the housing 10 of the sweeping robot 100 includes a separator 10a and a base plate 10b, the separator 10a is detachably installed on the upper surface of the base plate 10b, which is provided with the installation cavity 11 for installing the cyclone cone 30, the lower surface of the base plate 10b is partially recessed to form an accommodation cavity 12 for installing the ground brush 40, the base plate 10b is further provided with a dust suction channel 13 communicated with the accommodation cavity 12, and one end of the dust suction channel 13 far away from the accommodation cavity 12 is detachably connected with the separator 10 b. Because the installation cavity 11 is arranged on the separator 10a, and the separator 10a and the chassis 10b are detachably arranged, the separator 10a is conveniently detached from the chassis 10b, and further, the cleaning of dust, paper dust and other impurities in the installation cavity 11 is facilitated.
It should be noted that the separator 10a and the chassis 10b can be connected in various ways, such as by a snap connection, a latch connection, etc., which are not necessarily enumerated herein. The connection of the suction channel 13 to the separator 10a is understood to mean a pipe-to-pipe connection, which can be made in various ways, for example, directly by means of a plug-in connection, indirectly by means of an adapter, etc., to name a few.
